superconductors are brittle, hard to shape,
and high in normal -state electrical resistivity. On the other
hand, metals are in general ductile, formable, and have
low electrical resistivity and high thermal conductivity. In
contrast to metals, polymers in general have high electrical
resistivity and low thermal conductivity. Therefore, the
combination of a superconductor and a metal in the form
of a composite" is more attractive than the combination
of a superconductor and a polymer
